It helps so much after just a little while, and I thought I was okay on
75 mg, but as soon as my doctor got me up to 150, I felt much more like my "old self", and the 187.5 was a perfect dose for me. Other people I know take 300 mg a day. So if you don't feel better soon, check your dose with your doctor.
Good luck! We all struggle here, so everyone understands. And as for my weight gain, it could be the sweets I crave!
